Quick dismounting-mounting low-temperature heptafluoropropane pipe-network-free fire extinguishing device

Abstract

The invention relates to a quick dismounting-mounting low-temperature heptafluoropropane pipe-network-free fire extinguishing device. A bottle group cabin is arranged in a housing; the tops of two cabin doors are arched; semicircular pipe protection ports are formed at the arched tops; after the two cabin doors are closed, the two semicircular pipe protection ports are merged into a complete circular pipe protection port; two shaft brackets are arranged on a disk-shaped steel plate at the front of a bottom plate; a plurality of rollers are mounted on the two shaft brackets; a fire extinguishing agent bottle group is moved by horizontal rolling of the rollers; four American bracing frames are arranged on a lower plane of the bottom plate; a pedal hydraulic lifting mechanism is arranged in the middle of the lower plane of the bottom plate, and comprises a hydraulic pump, a hydraulic cylinder, a bracing arm, a lifting arm, a pedal plate and a manual unloading control rod; and the lifting arm is used for mounting and dismounting the fire extinguishing agent bottle group. The fire extinguishing device has the characteristics that the fire extinguishing device is quick to dismount and mount, pipe-network-free and movable. The fire extinguishing device is particularly suitable for operation in a narrow space, can allow a heptafluoropropane fire extinguishing agent to generate good atomization performance at a low temperature, can achieve a total flooding effect of the fire extinguishing agent in a protection space, and can extinguish a fire in the protection space.

Description

technical field [0001] The invention relates to a heptafluoropropane non-pipe network fire extinguishing device, in particular to a quick-disassembly type low-temperature heptafluoropropane non-pipe network fire extinguishing device. The device can make the heptafluoropropane fire extinguishing agent produce good atomization performance under low temperature conditions, realize the full flooding effect of the fire extinguishing agent in the protected space, and effectively extinguish the fire in the protected space. Background technique [0002] Heptafluoropropane (HFC-227ea) is a chemically synthesized clean gas fire extinguishing agent. It is colorless, odorless, non-toxic, non-conductive, and does not pollute the protected object. In particular, it has no destructive effect on the atmospheric ozone layer, and is an ideal substitute for haloalkane fire extinguishing agents at this stage. The fire extinguishing agent has high fire extinguishing efficiency, fast speed and ...

Problems solved by technology

[0011] In order to overcome the deficiencies of the existing fire extinguishing equipment, the purpose of the present invention is to provide a design scheme of a quick disassembly type low-temperature heptafluoropropane pipeless fire extinguishing device. The size is reduced. By setting a hydraulic lifting mechanism at the bottom of the movable bottle group support, the disassembly and assembly of the heptafluoropropane fire extinguishing agent gas storage cylinder is easy, labor-saving and flexible. By connecting the pipeline between the quick connector and the low-temperature atomizing nozzle, it overcomes the box The defect that the spraying of heptafluoropropane fire extinguishing agent directly from the body nozzle is not uniform enough
